The paper presents results of a study on the occurrence and localization of 30 field weed species in middle-eastern Poland. The species are considered to be regionally and overregionally rare and most of them grow on fertile soil (rendsine, alluvial soil). They include naturally rare species or species occurring on the border of geographical ranges (Anagallis arvensis var. azurea, Aphanes arvensis, Nigella arvensis) as well as species which are close to extinction (Bromus secatinus, Digitaria sanguinalis, Lolium remotum, Sherardia arvensis, Silene noctíflora). A group of important role are also expansive species talcing possession of habitats they have never grown in before (Asperugo procumhens, Falcaría vulgaris, Lathyrus tuberosus, Vicia grandiflora). Besides the list of localities (by provinces) general characteristics of distribution of each species and abundance and dynamic tolerance of localities are given.

This study compares results of observations of winter cereal cultures in the area of the Kotuń parish in two investigated periods (1979-1980 and 1989-1990). In cultures of rye, triticale and winter wheat, 124 species were recorded and investigated during the investigated period. Over 10 years the stability of occurrence and covering decreased in 34 species o f winter cultures. The species included very rare weeds, such as Agroslemma githago and Neslia paniculata, and many acid soil species, such as Scleranthus annuus, Anthemis arvensis, or Rumex acetosella. Plantago maior subsp. intermedia, Juncus hufonius and Filaginella uliginosa were species that have disappeared.

A list of 24 species of weeds was compiled on the basis of phytosocjological researches and floristic records of the biotypes of the Bug River geomorphological territories in the Podlasie region. Four hundred and twenty phytosocjological releves were carried out during the researches, in 1994-1995. The general characteristic of the arrangement of respective species localities are given. Alongside this, the state of preservation of these localities is presented. The results of the detailed analysis of the resources concern such units of classification as: Herniaria hirsuta, Herniaria glabra, Polycnemum arvense, Agrosiemma githago, Bromus secalinus, Melandrium noctiflorum.
